Task Analysis:
1. Using the matching and identification skills already present (see the prerequisites), interact with the student to verify that the 10 color samples can be matched and identified.
2. Choose two specific color items, preferably ones with high contrast to each other such as black and red. Place one example in front of the student, along with a container. Give the student all of the remainder of both colors. As in the matching exercise, guide the student in placing only the items that match the given example into the container.
3. Continue Step 2, adding another example to be matched and giving a third set of choices to the student.
4. Continue Step 3, adding a third example and incrementally giving the student more samples from which to choose until all the color cards have been given to the student to sort.
5. Continue Step 4, ensuring that the examples given to match are randomly selected. Continue until the objective is met.
